Multidetector computed tomography in transcatheter aortic valve implantation.
Aortic stenosis is a common disorder. Aortic valve replacement is indicated in symptomatic patients with severe aortic stenosis, as the prognosis of untreated patients is poor. Nevertheless, many patients pose a prohibitively high surgical risk and are not candidates for surgical valve replacement. Transcatheter aortic valve implantation (TAVI) is a novel method to treat selected high-risk pati...
متن کاملAutomated 3-dimensional aortic annular assessment by multidetector computed tomography in transcatheter aortic valve implantation.
OBJECTIVES This study sought to evaluate the accuracy, reproducibility, and predictive value for post-procedural aortic regurgitation (AR) of an automated multidetector computed tomography (MDCT) post-processing imaging software, 3mensio Valves (version 5.1.sp1, 3mensio Medical Imaging BV, the Netherlands), in the assessment of patients undergoing transcatheter aortic valve implantation (TAVI)....
متن کاملRole of preprocedural computed tomography in transcatheter aortic valve implantation.
UNLABELLED Transcatheter aortic valve implantation (TAVI) is currently considered an acceptable alternative for the treatment of patients with severe aortic stenosis and a high perioperative risk or a contraindication for open surgery. The benefit of TAVI significantly outweighs the risk of the procedure in patients requiring treatment that are not suitable for open surgery, and leads to a lowe...
متن کاملMultidetector row computed tomography parameters associated with paravalvular regurgitation after transcatheter aortic valve implantation.
Multidetector row computed tomographic (MDCT) assessment of aortic annulus dimensions and frame position and deployment have been associated with paravalvular aortic regurgitation (PAVR) after transcatheter aortic valve implantation (TAVI). The present evaluation investigated the (pre- and postprocedure) MDCT associates of PAVR ≥2+. In total, 123 patients referred for TAVI underwent clinical ev...
متن کاملTranscatheter mitral valve-in-valve implantation: role of preprocedural multidetector computed tomography.
A reoperação valvular mitral por disfunção de prótese biológica associa-se a elevada morbimortalidade. Como alternativa para os doentes de elevado risco cirúrgico, pode-se considerar a implantação transcateter de prótese valvular invertida em posição mitral pela técnica valve-in-valve. Baseados na experiência de três casos clínicos com implantação de dupla prótese (aórtica e mitral) transcatete...
